Study on Reducing the Volatile Organic Compounds Emissions from Different Processing Particleboards
The aim of this paper is to study on how to control VOC emissions from wood-based panel manufacturing.Total volatile organic compounds (TVOC) emissions from larch particleboard under different processing conditions were collected by an environmental chamber.VOC samples were prepared by desiccator,adsorbed by activated carbon,desorpted with Methylene dichloride and measured by GC/MS.The result showed that the optimal process parameters were single-layer structure,moisture content of 6％,density of 0.60 g·cm-3,thickness of 8mm,resin content of 7％,hot-pressing time of 4min.TVOC increased with board density going up,hot-pressing time increasing,moisture content and resin content rising.The predominant compounds emissions from the particleboards are aromatic compound and hydrocarbon.24 kinds of compounds were identified from the standard board.With hydrocarbon decreasing,aromatic VOC type increased.
